As back-end'a used JEE (Spring), front-end is designed for devices with mandatory support for JS (for the rest there is a separate version), so the jsp and the like will only interfere. The calculation is done on RestFul, and therefore, for client-side AngularJS was chosen, but soon with the release of Angular2 began to wonder:
+ how long will last the first version ?
+ what a miracle is Angular2? well, not similar to the first, and where there is a client angular (here
), where only the ground is connected it is not clear what lib, and they provoke some errors ?
